State Rep. Betty Price took to the airwaves on Monday to urge conservative voters to defend her husband's U.S. House seat, as antsy Republicans aim to prevent a surging Democrat from notching an upset victory.

The Roswell Republican is featured on radio spots airing through the April 18 election calling on supporters to ensure a "strong conservative representative" succeeds her husband, Tom Price, who is now Donald Trump's health secretary.

"It's so important that we elect a conservative to fill Tom's seat, to continue Tom's fight for lower spending, lower taxes and a strong defense against America's enemies," she said.

The ads are the latest salvo from the Congressional Leadership Fund, a super PAC with ties to House leadership that has spent $2.2 million on ads - and $3 million overall - trying to rev up GOP voters and deflate Democrat Jon Ossoff's candidacy.

The seat has been in GOP hands for decades but Democrats are hoping Trump's tepid performance in the 6th District, which spans from east Cobb to north DeKalb, gives them a chance to flip it. They have pinned their hopes on Ossoff, a 30-year-old former Congressional aide who raised an epic $8.3 million since entering the race in January and is aiming for an outright win to avoid a runoff.

Betty Price, who like her husband is a physician, has not endorsed any of the 11 Republicans in the 18-candidate contest but urged conservatives to elect a "proven Republican." She also considered joining the field, before announcing about an hour before qualifying ended that she would not mount a campaign.
